  <synopsis>

    local attacker to execute arbitrary code.

  <affected>
    <package name="net-news/blam" auto="yes" arch="*">

  <background>
    <p>
    Blam is an RSS and Atom feed reader for GNOME written in C#.
    </p>
  </background>
  <description>
    <p>
    The "/usr/bin/blam" script sets the "LD_LIBRARY_PATH" environment
    variable incorrectly, which might result in the current working
    directory (.) being included when searching for dynamically linked
    libraries of the Mono Runtime application.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could entice a user to run Blam in a directory
    containing a specially crafted library file which could result in the
    execution of arbitrary code with the privileges of the user running
    Blam.
    </p>
  </impact>
  <workaround>
    <p>
    Do not run Blam from an untrusted working directory.
    </p>
  </workaround>
  <resolution>
    <p>
    All Blam users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-news/blam-1.8.4"</code>
  </resolution>
